V型尾翼布局弹性体飞机操纵性分析

使用静气动弹性分析方法,对双尾撑V型尾翼布局飞机纵向静气动弹性特性随飞行动压、迎角、尾撑纵向弯曲刚度的变化趋势进行了分析,以期为类似布局飞机的设计提供参考。尾撑结构刚度对飞机的俯仰、偏航的操纵效率都有较大影响,需要结合飞行动压范围和质量要求合理选择尾撑结构的材料和尺寸,在设计时,严格控制尾撑的刚度指标。

Analysis of the Control Characteristics of V-Empennage Flexible Wing Aircraft

Using static aeroelastic analysis method,the analysis of the changing tendency of longitude aeroelastic characteristic to flight velocity pressure,angle of attack and the stiffness of the tail boom was made to a twin-tail boom and V configuration empennage aircraft,willing to give a reference to the designing of aircrafts with the same configuration.It shows that the stiffness of tail boom has a big influence on the efficiency of pitching and griping,the design of tail boom should be considered with both the range of dynamic pressure and weight restriction,the structural stiffness index should be strictly checked.
